Latest version of Premiere Pro vers 12.0.1 keeps coming up with error# 99 in export
I'm trying to export a video for a client, and the settings that I used in the previous version which worked fine, now keeps coming up with an Error 99 message. I tried a variety of different options, turned MRQ on and off, etc... and nothing seems to work. Anyone else experiencing this export issue? Since this upgrade I have been unable to export any videos including the ones for my clients. The issue is not only for this video.
Please give tips/actions to fix this problem. I really regret upgrading as this is hurting my business.
Thank you.
